Description

Hibbertia cymosa is a shrub that typically grows to a height of up to 1.4 m (4 ft 7 in), its branches and leaves densely covered with star-shaped and long white hairs. The leaves are elliptic, 40–53 mm (1.6–2.1 in) long and 12–15 mm (0.47–0.59 in) wide on a petiole 1.6–2.8 mm (0.063–0.110 in) long. The flowers are borne singly, in pairs or threes in leaf axils on a thin peduncle 6.5–2.5 mm (0.256–0.098 in) long, with egg-shaped bracts 1.5–2 mm (0.059–0.079 in) long. The two outer sepal lobes are 2.6–3.8 mm (0.10–0.15 in) long and the three inner ones are 4.7–5.6 mm (0.19–0.22 in) long. The five petals are egg-shaped with the narrower end towards the base, yellow, 7–8 mm (0.28–0.31 in) long and there are fifty to eighty stamens arranged around the three carpels, each carpel with two ovules. Flowering occurs around June. [2] [3]

Taxonomy

Hibbertia cymosa was first formally described in 1991 by Sally T. Reynolds in the journal Austrobaileya from specimens collected by Anthony Bean near Jowalbinna (near Laura) in 1990. [4] The specific epithet (cymosa) refers to the cymose arrangement of the flowers. [2]

Distribution and habitat

This hibbertia is only known from the type location where the species grows near a creek. [2]

Conservation status

Goodenia cymosa is classified as "vulnerable" under the Queensland Government Nature Conservation Act 1992 . [5]
